Miglustat Gen.Orph contains the active substance miglustat which belongs to a group of medicines that affect metabolism. It is used to treat two conditions:
In type 1 Gaucher disease, a substance called glucosylceramide is not removed from your body. It starts to build up in certain cells of the body’s immune system. This can result in liver and spleen enlargement, changes in the blood and bone disease.
The usual treatment for type 1 Gaucher disease is enzyme replacement therapy. Miglustat Gen.Orph is only used when a patient is considered unsuitable for treatment with enzyme replacement therapy.
If you have Niemann-Pick type C disease, fats such as glycosphingolipids build up in the cells of your brain. This can result in disturbances in neurological functions such as slow eye movements, balance, swallowing, and memory, and in seizures.
Miglustat Gen.Orph works by inhibiting the enzyme called ‘glucosylceramide synthase’ which is responsible for the first step in the synthesis of most glycosphingolipids.
Talk to your doctor or pharmacist before taking Miglustat Gen.Orph
Your doctor will perform the following tests before treatment and during treatment with Miglustat Gen.Orph:
The reason for these tests is that some patients have had tingling or numbness in the hands and feet, or a decrease in body weight, while taking Miglustat Gen.Orph. The tests will help the doctor decide whether these effects are due to your disease or other existing conditions, or due to side effects of Miglustat Gen.Orph (see section 4 for further details).
If you have diarrhoea, your doctor may ask you to change your diet to reduce your lactose and carbohydrate intake such as sucrose (cane sugar), or not to take Miglustat Gen.Orph together with food, or to temporarily reduce your dose. In some cases the doctor may prescribe anti-diarrhoeal medicines such as loperamide. If your diarrhoea does not respond to these measures, or if you have any other abdominal complaint, consult your doctor. In such case, your doctor may decide to conduct further investigations.
Male patients should use reliable birth control methods during their treatment with Miglustat Gen.Orph, and for 3 months after finishing treatment.
Do not give this medicine to children and adolescents (below 18 years old) with type 1 Gaucher disease because it is not known if it works in this disease.

Most serious side effects:
Some patients have had tingling or numbness in the hands and feet (seen commonly). They could be signs of peripheral neuropathy, due to side effects of Miglustat Gen.Orph or they could be due to existing conditions. Your doctor will perform some tests before and during treatment with Miglustat Gen.Orph to assess this (see section 2).
If you do get any of these effects, please seek medical advice from your doctor as soon as possible.
